For melanoma specifically, a simple way to remember the warning signs is to remember the A-B-C-D-Es of melanoma—

  1. Asymmetrical: Does the mole or spot have an irregular shape with two parts that look very different?
  2. Border: Is the border irregular or jagged?
  3. Color: Is the color uneven?
  4. Diameter: Is the mole or spot larger than the size of a pea?
  5. Evolving: Has the mole or spot changed during the past few weeks or months?
